Hi Guys,
I have recently started using eview for a project in college. I am using Hamilton's 1989 model that was modified in 2002 by Garcia and Schaller to try and show that interest rates have a different effects dependent on what state the interest rate change happens in. So I have got the Gnp data for the US and preformed a 100*dlog(gnp) on it and let the series equal g. I have got the Federal funds rate and and preformed a dlog(fed) on it and let the series equal f. Please correct me if I have made any mistakes so far. I then go to quick/estimate equation. I change the method to switchreg. I put g followed by c in the dependent variable box. ar(1) ar(2) ar(3) ar(4) goes in the non-switching box. This is the part I'm not sure about. Where do I put the interest rate? I have put it in the Probability regressioners box after c like f(-1) f(-2) f(-3) f(-4). Is that correct? When I get the filters graph it looks correct. I'm also unsure how to interpret the data. What coefficient means a change in the interest rate leads to a change in the GNP in either state?
Any help would be appreciated. Below is the output I got.
